HARTFORD, CONNECTICUT.

COPYING-PRESS.

To all whom it may concern:

Be it known that I, SIMON H. STUPAKOFF,

' of Hartford,Connecticut, have invented anew and useful Letter-CopyingPress, of which the following description and claims constitute thespecification, and which is illustrated by the accompanying two sheetsof drawings.

This invention is a copying-press, consisting, mainly, of two plates orparts which are adapted to be drawn together by wedges.

Figure 1 is a perspective view of the press, presenting that side whichreceives the letterbook. F1g. 2 is avertical section of the oppositeside of the press, looking toward the middle of the press, and being onthe line a a of Figs. 3, 4, and 5. Figs. 3, 4, and 5 are verticalsections of the press on the lines I) b, c c, and d (2, respectively, ofFig. 2.

The numeral 1 indicates the upper part,and 2 denotes thelower part,-ofthe press. The upper part is made of two pieces fastened together byscrews, the space between the two being the housing for sundry of theoperating parts of the press. The upper part, 1, is also provided withthe sides 3 and 4, and those sides are provided with the horizontalflanges 5 and 6, respectively. The lower part, 2, is provided with thesides 7 and 8, and those sides are provided with the horizontal flanges9 and 10, respectively. The wedge 11 works between the flanges 5 and 9,and the similar Wedge, 12, works between the flanges6 and 10. I preferto provide the opposing faces of the two pairs of flanges withfriction-rollers, as shown in Fig. 4, but the wedges may work betweenproperly-formed surfaces without such rollers. Each wedge has a rack cutin its up per side adjacent to one end, as shown in Fig.

4, and those racks engage with the pinions 13 and 14, which are fastenedto the shaft 15. That shaft is also provided with the wormgear 16, whichmeshes with the worm 17 on the shaft 18, and the latter shaft isprovided with the square head 19 for the reception of a Wrench.

The mode of operation is as follows: A letatent No. 353,606, datedNovember 30,1886.

. Serial No. 196,656. (No model.)

terbook being introduced into the press, through the opening shown inFig. 1, the square head 19 is turned with a wrench. That turningoperates, through the worm, the wormgear, the shaft, the pinions, theracks, and the wedges, to draw the upperand thelo'wer parts of the presspowerfully together, and thus to adequately press the letter bookbetween them.

The shaft 18 may be fixed in a vertical position, instead of ahorizontal, and, indeed, a vertical position is probably preferable tothe other. So, also, the two wedges maybe worked by independent screwswithout the intervention of any shaft operating upon both of them, orthey may be worked by independent cams or levers, or by such deviceswork ing together upon both wedges. Moreover, the upper part, 1, may bemade detachable from the sides 3 and 4, so as to be readily lifted awayfrom the other parts of the press, or turned upon a hinge, and afterwardattached to the sides 3 and 4, so as to operate integrally therewith. Aninferior result may also be reached with one wedge only, the oppositesides of the two main parts of the press being held together by a hinge,or similarly.

I claim as my invention 1. In a copyinr-press, the combination of parts1 and 2, constructed substantially as described, and arranged to beforcedtoward each other by the horizontal movements of inclinedsurfaces, between flanges appurtenant to those two parts, allsubstantially as described.

2. In a copying-press, the combination of thepart 1, provided with thesides 3 and 4 and the flanges 5 and 6, the part 2, provided with SIMONH. STUPAKOFF.
